Ready for a serious challenge? We've got an ultra run through the Ashdown Forest and South Downs. Pick your discipline - triathlon, duathlon, aquabike, aquathlon, swim or run - and choose a distance from middle to ultra. Recruit your friends and celebrate completing your challenge in our festival village.

Venue

The childhood home of Anne Boleyn, Hever Castle is a stunning location for a race. Swim from The Loggia with its Nymph’s Fountain inspired by the Trevi Fountain in Rome. Run through stunning castle grounds and surrounding villages, cycle through the Ashdown Forest and South Downs.

Throughout the weekend, athletes and spectators will be able to enjoy a fun-packed festival village featuring live music, shopping, food and drink, children’s entertainment, yoga and more.
